Hi Andy
Heres a scoop from the bin there done that, and would do it again
My heads had custom machined SS valves, big vigin stock valves that get machined to a spec. The rockers pads where slitely decked to equal all the base hieghts, and all custom guides installed. I had looked at a 911 rocker set up, but way too expensive, so I did some measuring and a Buss motor T1V, has the same srocker set up as my 2.0l but uses the smaller 8mm compared to the 9mm 911, (I might be wrong on the sizes, its early in the morning and I am going from memory).
Check a VW swivle rocker price now we are talking.
Something to stress here wich is not related to your motor because it has already been built, rocker geometry is directly related to your cyl heights. Push rods need to be adjusted for length, I don't see an option here, after compression is set the head bolted on, the rocker deck and lifter are unajustable, leaves the push rod. My pushrods where sized, one at a time, to have @ half lift the rocker @ level, strait 90deg at valve stem. swivle foot strait line with valve. This will cure a lot of guide wear/smoke issues down the road. Back in the day I used a Jewel lathe to trim down the pushrods, never needed longer rod, but now I am sure the push rods can be found with adjustment screws, although this is expensive.
I have had a quiet, reliable, min maintenance/adjustment needed, setup for ten years now, on a mild hopped motor, no failure in the valve train watsoever, not a lot of 914s can say that.
Would do the buss thing again if I was going to keep my 2.0l.
I'm late for work!
Regards and thanx for letting me use your site Andy
